You’ve got to pay attention to a professor named Siddhartha. But this is Verma not Gautama
and he’s currently studying fluid dynamics at Florida Atlantic University.
In this video, he explains and demonstrates clearly what all this COVID particle transmission and control is all about. Notice that masks are all about protecting others from you, not you from others. So those nervous Nellies walking up my way as I walk down Broadway hill and stop to put on their masks are wasting their time.
It’s not long, and the images of particles being projected are pretty amazing.
